Pig Farm Wastewater Treatment Engineering Design
Abstract With the rapid development of livestock and poultry breeding in recent years, the livestock and poultry breeding wastewater emissions gradually increased, caused seriously negative impact to agricultural ecological environment and water quality. This design task is the pig farm breeding wastewater treatment engineering design, that requires the overall design of wastewater treatment. Pig farm wastewater inlet water quality provided as follows: Q = 900 m3/d, BOD5 = 3000 mg/L, COD = 5000 mg/L, SS = 1000 mg/L, NH3-N = 300 mg/L, TP = 30 mg/L, pH = 6 ~ 9. Design for the standard of the livestock and poultry breeding industry pollutant emission (GB18596-2001) emissions requirements.
Mainly used in the design of the sewage treatment process is that Remove ammonia - Anaerobic reaction - Coagulation precipitation- Disinfection- Draining. It involves the concrete operation, such as the major structures, and their size in calculation. The results of design are need through auto CAD ,including sewage plant layout, main treatment structures).
